CP-120 VS SCP-120

[hexumjunkie]

I have a two rw-20'S at opposite end's of a 60" long 30" deep tank. The one is having motor issues making the controller not power on. (i have cross tested it). Was going to replace it with a new rw-20. But now im thinking about a 120 cp or scp. What's the diff and will this setup be ok?

I think the CSP is the new model with a different motor
